This is not about how I planned my wedding. In this article I’ll explain how I created a very basic RSVP system to remind the guests of the wedding date and inform their table numbers. Not only that, I’ll cover how I distributed the wedding day tasks within a group of family members and how I reminded them by sending mobile notifications at the time on which the task required to be performed. > In this section I’ll explain how I created RSVP website along with the SMS notification (guests) and email notification (host) system. First I’ll briefly explain the flow of the design. I assigned each guest a unique id. You can easily generate bulk UUID using this website. After generating sufficient UUIDs for the number of guests, you will notice that only the first 8 characters of the IDs were unique. Therefore you can remove the remaining digits and use only the first 8 characters.
